The trocar adapted includes a trocar sleeve positioned for reception within the longitudinal opening and a trocar valve adapted to receive a surgical instrument in fluid tight relation therewith. The access housing may include a seal adapted to form a seal about each of the surgeon~s arm and the trocar sleeve. The seal is adapted to close in absence of the surgeon~s arm or the trocar sleeve.
